About Mangrove
We exist to make problems economic to solve that never were before. An AI-native engineering practice: one accountable lead end to end, a named specialist bench on demand, and every engagement priced against a signed done-test.
Kevin Maguire
Founder
20+ years as CTO and CIO across payments, capital markets, energy, financial services, and cybersecurity. CISSP. CISO at Earthport, responsible for security at Spark, and built CyberSee, a security risk assessment platform. Cambridge Judge CTO Programme. Edinburgh CS. Mangrove brings that context to a senior lead directing AI, with a specialist bench on demand, accountable end to end.
Full context, single accountability
Every engagement has one accountable lead directing AI, holding full context end to end, with specialists pulled in where the work needs them. Handoffs are the exception, so almost nothing is lost in them.
A bigger project traditionally means a bigger team, and a bigger team means coordination overhead: slower delivery, higher cost. A senior lead directing AI takes the overhead out instead, and every decision is made by someone who understands the whole system.
Quality
Every delivery includes comprehensive tests, documentation, and clean code, checked by automated quality gates on every commit.
Continuity
The code is always handover-ready, with documentation counted in the weekly report, so continuity is built into the process rather than promised.
Accountability
Fixed price against a signed done-test, delivered in full or your money back. We stand behind every engagement.
The bench, on demand
Security is in-house: twenty years of it, from BAE Systems to running a ransomware defence company, CISSP, and the CISO seat at a payments business moving £17bn for the world's largest banks. It is designed in from the first architecture decision rather than bought in at the end.
Where an engagement needs depth beyond that, we bring in named senior specialists for that work, under the same single-accountability model. Designis Hannah's: the Grove identity, the icon set, and the diagrams across this site are her work.
The grove is how we picture it: one connected root system, visible work above the waterline, tests, documentation, security, and infrastructure below. Specialists join that root system for the engagement; they never form a second team to coordinate.
Why this works
The people behind it have sat in the CTO and CIO chairs. Built the teams, run the integrations, owned the outcomes.
That experience, combined with AI-native tooling, is what makes fixed-price commitments against a signed done-test possible, and what makes them safe. We wrote a manifesto about what changed and what it means.
Work with us
An assessment is the lowest-friction way in: senior technical judgment, fixed price, a deliverable you can put in front of a board.
